Hardmetal Widia
Purchase of scrap and waste of Widia (tungsten carbide) for tungsten recovery: used inserts, drills, offcuts and grinding sludge. Fast quotations and collection throughout the territory.
Hardmetal made of tungsten carbide sintered with a cobalt binder: extreme hardness and wear resistance. Reference markets: cutting tools, dies, mining, drilling and tungsten recovery.
- Forms inserts · drills · offcuts · sludge
- Density ≈ 14 – 15 g/cm³
- Hardness 1300 – 1800 HV
Main elements
| Tungsten carbide (WC) | 70 – 97 % |
|---|---|
| Cobalt (Co) – binder | 3 – 30 % |
| Tantalum carbide (TaC) | 0 – 8 % (mixed grades) |
| Titanium carbide (TiC) | 0 – 12 % (mixed grades) |
| Niobium carbide (NbC) | traces – a few % |
| Nickel / Chromium (alt. binders) | in cobalt-free grades |
Indicative values: the composition and cobalt content vary widely with the grade. The commercial value depends on the tungsten and cobalt content, certified by analysis for each batch.
Physical and mechanical data
| Density | ≈ 13.5 – 15.2 g/cm³ |
|---|---|
| Hardness | 1300 – 1800 HV (≈ 89 – 93 HRA) |
| Flexural strength | ≈ 1500 – 3500 MPa |
| Elastic modulus | ≈ 450 – 650 GPa |
| Structure | sintered carbides in a metallic matrix |
| Recoverable tungsten content | high (core of the value) |
Properties depend on the grade (WC grain size and binder percentage).
